Hm, Reaper's output shows: GPU 956.7MH/s, shares: 0|0, stale 0%, ~0 kH/s, 906s

I bumped up the aggression and threads per GPU which really helped the initial number shoot up, but the actual process rate is still showing 0 kH/s.

FYI, I'm running Ubuntu 12.10 on a NVS 4200M that tells me it has 48 CUDA cores, with the official Nvidia drivers  from http://www.nvidia.com/object/unix.html

I'm not having much luck finding Nvidia-related Reaper discussions :-/

Once again, this is not your GPU hashrate, this is the rate at which your GPU is erroring.  drop down thread concurrency, work size, aggression, etc.

Well, that is certainly nice to know! Sure would have saved me some time if it had been outlined in the manual or simply printed out as "GPU Error Rate"

After significantly lowering my config values, now I seem to actually be processing work!

Ya, that's just errors. If a single nvidia could pull 1gh/s, we'd all be using them!  Wink Glad you got it fixed.

 I tried Reaper and cgminer. cgminer nearly freezes my desktop and gives me 31 kH/s(that's the value burnside shows me), with this command

Code:
cgminer --scrypt -o http://ltc.kattare.com:9332/ -u turvarya.1 -p x --thread-concurrency 4800 -I 18 -g 1 -w 128

when I use Reaper i just get about 20 kH/s, but can do other stuff, with this configuration

litecoin.conf
Code:
protocol litecoin

worksize 256
aggression 10
threads_per_gpu 2
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 4800
long_polling yes

reaper.conf
Code:
kernel reaper.cl
save_binaries yes
enable_graceful_shutdown no
long_polling yes
platform 0
device 0

mine litecoin

Is that even near of what I should get? Any suggestions?
(I have a 6870)

After significantly lowering my config values, now I seem to actually be processing work!

Had a similar issue myself when getting started with gpu mining on my NVidia GT555M, had to bring down the GPU thread concurrency down from 6144 down to 2048 initially to get it hashing properly and then steadily got up to 4096 where its at now, though the stale share count is pretty high on gpu mining (between 40-50%)..

This is apparently linked to the number of shaders and the thread queue depth for each shader - the shader count is woefully low on NVidia GPUs - mine is 192. Wondering if the magic number is 192 shaders multiplied by sharethreads 18 = 3456? Will have a stab at this to see if it helps..

i have a pair of sli'd 560ti's in an old gaming rig that i mine on for one pool. i know sli slows it down a bit, but with each having 384 shaders, i sit around 150mh/s combined.

turvarya, maybe these two threads will help. both have multiple posts from people mining with cgminer or reaper on 6870s. looks to me your concurrency and a few other settings might be off.

ok, thanks, helped me a lot
still it's a pain in the ass to try stuff out, since it often nearly freezes my desktop.
I got about 360kh/h top and avg of about 300kh/h over night, when i am afk, but haven't found a configuration, yet, that gives me good kh/h and let me still work on it. But I guess it#s a matter of more tries. Never hat real problems with btc-mining

setting for my best result, if anyone needs it(the worksize of 64 is strange, but it works)

Code:
cgminer --scrypt ^
-o http://ltc.kattare.com:9332/ ^
-u turvarya.1 -p x ^
--thread-concurrency 6720 ^
-I 16 ^
-g 1 ^
-w 64

I'm gettting a high rate of stales according to the web page- Round Shares: 200 (47.5% stale)

I'm using the latest cgminer with this readout when stopping it:

 [2013-03-08 08:22:40] Started at [2013-03-08 00:01:02]

 [2013-03-08 08:22:40] Rejected difficulty shares: 24583
 [2013-03-08 08:22:40] Reject ratio: 16.1%
 [2013-03-08 08:22:40] Hardware errors: 0
 [2013-03-08 08:22:40] Efficiency (accepted / queued): 758%

 [2013-03-08 08:22:40] Work Utility (diff1 shares solved / min): 9.82/min

16% is really high, I think. Help?

why is this so hard!!!!  tl:dr, i broke litecoin-qt trying to get the miner to work

i got the bitcoin miner to work somehow... i've been trying to get the litecoin miner to run for hours now.  every place i've seen that has direction, i dont know what they're talking about.  i'm not bad with computers but i've never used cmd or .conf or .bat and i dont know what i'm doing.  i somehow even made it so litcoin-qt didnt work so now i'm re-downloading the blocks.  i probably wont be able to get on until tomorrow.

Same here, 15.76% rejection rate all of a sudden today. Using reaper, normally have around 5-6% stale.

Reaper is only showing 7.1%, pool showing 16% now. The stale stats might just be off.

my rewards were also off equivalent to the stales they reported. not good for me

Yea, my rewards seem to be askew from the stales too.

Well, I guess I'm not the only one. My rewards are off, too. I wonder if he's having a DOS attack again. I quit mining a while back b/c it was so bad.

Burnside, any news?

I haven't received any notices from the DoS provider.

I have higher than normal stales too.  Can't wait to get the new server online.

In the meantime I have tweaked the RAM allotment for MySQL a little bit.  Gave it a bigger table_cache and bigger key_buffer_size.  (based on recommendations from an analysis tool I have.)  Hopefully that'll help.

Cheers.

I'm not a Coinbase fan -- I placed a buy order, they took the funds out of my account, then a week later the price went up and they canceled the buy and closed my account.  You've been warned.  Use a different exchange.
